| SINGULAR. | PLURAL. | |

56. In words of more than one syllable, if the nominative ends in aċ or eaċ, the genitive singular is formed by changing aċ or eaċ into aiġ or iġ respectively. With a few exceptions, the nominative plural of these nouns is like the genitive singular. The other cases are quite regular.
In monosyllables ċ is not changed into ġ; as bruaċ, a brink, gen. bruaiċ.
N.B.—In all declensions in words of more than one syllable aċ and eaċ, when attenuated, become aiġ and iġ; and aiġ and iġ when made broad become aċ and eaċ. See dat. pl. of marcaċ and coileaċ.
Examples.
| 57. | marcaċ, a horseman. | |
| SINGULAR. | PLURAL. | |
| Nom. & Acc. | marcaċ | marcaiġ |
| Gen. | marcaiġ | marcaċ |
| Dat. | marcaċ | marcaċaiḃ |
| Voc. | a ṁarcaiġ | a ṁarcaċa |
N.B.—The majority of nouns in aċ belonging to this declension are declined like marcaċ.
